Turn off SR at high shutter speeds?

When shooting hand held at high shutter speeds like 1/4000, 1/8000 is there any advantage in turning off SR or better to keep SR on? Using K-5IIs.

thanks, Bernie

My answer is yes. I turn that off faster than 1/500

What!? A PF link that works!? Thanks DPR!

Well almost - remove the trailing "--"

As for SR, I haven't seen any difference myself at high speeds. But if i forget to turn it on again.... And mount something like the 77 for candid portraits in low light: Big diff! In other words, i just leave it on all the time.

Re: Turn off SR at high shutter speeds?

When in doubt, what effort does it take to turn it off? I never use SR unless I specifically need it.

Was it any better/worse with SR On?  Or do you turn it off just because? (serious question)

My guess is over such a short shutter speed it should make little difference, but I wouldn't rule it out.

What benefit do you think you are getting by turning it off ?

In theory if the camera isn't moving the SR doesn't move the sensor. So there is no harm to it being on for a long exposure on tripod.

If the exposure is very brief now far the SR mechanism moves the sensor makes not difference.

If you turn SR off the risk is that you find you needed it after the shot is taken.

AF speed might increase, if not bound by the lens' AF speed to begin with.

It was posted a long time ago that turning off auto setting features, camera features, and minimizing the number of AF points helped with AF speed. I don't know if this is still true, but at the time people thought that it did increase AF speed in some lenses.

Thank you

When Pentax first came out with SR, it was recommended to turn it off at higher shutter speeds. I don't recall who posted that, but perhaps it was John C. Pentax. When I had the K20D, with a dedicated SR button, I did turn it off. Now that the SR feature is buried in menus, I just leave it on.

Thanks!

I wasn't aware that the link filters are no longer active until I read your post.  Good move on DPR's part - the filtering was not really effective as it was relatively easy to work around it and it seemed somewhat childish...

Re: Turn off SR at high shutter speeds?

With the K5 series cameras I was careful to turn SR off when shooting from a tripod (high shutter speed never seemed to matter in the first place).  A couple of times I forgot to turn SR off and didn't notice I had left it on until looking at exif later.  The SR didn't seem detrimental to the shots even on the tripod so I just left it set to on from there forward.  I'm not sure with the K-3 so I'll try some test with the SR on and off at high shutter and from a tripod also working from the focus peaking while I still have the Sigma 35.  Should be an interesting test.

Cheers.

When hand holding a 1050mm equiv lens 1/500th sec is far too slow and absolutely requires SR... at 1/1250th sec it'd probably be fine with the SR off unless you're not a very stable person. I usually just leave it on right up to 1/8000th even if it does nothing for me.

+1 accept on the long exposure there is the chance for drift in the gyros making it correct when there is nothing to correct
